I am trying to build an app that contains chat, but the error message appears:

[ERROR:flutter/lib/ui/ui_dart_state.cc(186)] Unhandled Exception: [cloud_firestore/permission-denied] The caller does not have permission to execute the specified operation.

My firebase rules:

rules_version = '2';
service cloud.firestore {
  match /databases/{database}/documents {
  
match /users/{uid}{
allow write: if request.auth != null && request.auth.uid == uid;
}

match /users/{uid}{
allow read: if request.auth != null;
}

match /chat/{document=**}{
    allow read: if request.auth != null;
    }
  }
}

enter image description here

as seen in the picture above, when I write a message and send it, it doesn't appear in the screen, and the error message is written in terminal

You can make your rule as per below. It is also secure

rules_version = '2';
service cloud.firestore {
  match /databases/{database}/documents {
    match /{document=**} {
      allow read, write: if request.auth != null;
    }
  }
}

rules_version = '2';
service cloud.firestore {
  match /databases/{database}/documents {
    match /{document=**} {
      allow read, 
      write: if true;
     }
  }
}

This can be used when there is no need for authentication access.

you should update your Firestore rules try to change date for next month or year

from : request.time < timestamp.date(2022, 7, 4);

to :
request.time < timestamp.date(2022, 8, 4);

rules_version = '2';

service cloud.firestore {

  match /databases/{database}/documents {

    match /{document=**} {

      allow read, write: if

          request.time < timestamp.date(2022, 8, 4);

    }

  }

}
